Dear developers,
I have been trying out the master branch and am somewhat frequently
getting segfaults with the error below in the dialogue box. It often
seems to happen when typing math commands that LyX doesn't know about.
I don't know much about this situation so I don't know if this is
helpful for debugging. I can run with some debug flags going forward if
someone tells me which ones to set.
best,
Alex
